“…The largest cohort of patients undergoing a laparoscopical resection contained six patients, none of whom had a preoperative histological diagnosis of a schwannoma [4]. A few teams have successfully proceeded to a robot-assisted resection [10][11][12]13]. These publications have demonstrated the feasibility and the safety of such a tumor resection/excision with the assistance of a robotic system, sparing the continuity and the further normal function of the neural structure, as described by Perrin et al [10].…”

“…In contrast to literature reports about schwannomas in the retroperitoneal space, only case reports or small series of patients with schwannomas of the obturator nerve have been reported in the literature, describing mostly an open surgical or (seldom) a laparoscopical or robotic approach [7][8][9][10][11]. The largest cohort of patients undergoing a laparoscopical resection contained six patients, none of whom had a preoperative histological diagnosis of a schwannoma [4].…”

“…Robotic systems have been gradually applied to the removal of benign presacral tumors, as they can provide improved three-dimensional visualization and more flexible and stable manipulation. It has also been suggested that robotic laparoscopic resection of pelvic schwannomas may have advantages in preserving the function of the nerves (18,19). Due to the learning curve, robotic laparoscopic resection should be limited to experienced surgeons in high-volume centers, which somewhat limits the progress of these systems.…”

Schwannoma is a benign tumor of the nerve sheath originating from Schwann cells. The tumor rarely occurs in the sciatic nerve. The patient in the present case report was a 58-year-old woman presenting with pain in the right hip and leg, as well as numbness of the right lower limb. Magnetic resonance imaging revealed a solid tumor of 2.9 cm in diameter in the right pelvic space. The mass was considered to be a neurogenic tumor originating from the right sciatic nerve. Total laparoscopic surgery was performed to safely separate the tumor from the surrounding tissues, with preservation of the right sciatic nerve. The pathological result suggested a schwannoma. The patient recovered well with a transient numbness in the right heel. The laparoscopic approach used for this intrapelvic schwannoma of the sciatic nerve was safe and feasible, with the advantages of a magnified surgical field and small skin incision. However, the specific surgical approach should be based on the detailed condition of each patient and the experience of the surgeon with regard to laparoscopic surgery on benign presacral tumors and rectal tumors.

“…20 One patient experienced a temporary motor neurological deficit after resection of an obturator schwannoma, and no patients experienced significant permanent neurological deficits. 5,7,10,17,[21][22][23][24][25][26][27][28][29][30][31][32][33] The present review is limited by the small number of reported cases of robotically resected retroperitoneal nerve sheath tumors. All included studies were case reports or series published over the course of more than 20 years, and therefore data such as EBL, operative times, and duration of hospitalization were not available for all patients.…”

BACKGROUND: Retroperitoneal nerve sheath tumors present a surgical challenge. Despite potential advantages, robotic surgery for these tumors has been limited. Identifying and sparing functional nerve fascicles during resection can be difficult, increasing the risk of neurological morbidity. OBJECTIVE: To review the literature regarding robotic resection of retroperitoneal nerve sheath tumors and retrospectively analyze our experience with robotic resection of these tumors using a manual electromyographic probe to identify and preserve functional nerve fascicles. METHODS: We retrospectively analyzed the clinical courses of 3 patients with retroperitoneal tumors treated at the National Institutes of Health by a multidisciplinary team using the da Vinci Xi system. Parent motor nerve fascicles were identified intraoperatively with a bipolar neurostimulation probe inserted through a manual port, permitting tumor resection with motor fascicle preservation. RESULTS: Two patients with neurofibromatosis type 1 underwent surgery for retroperitoneal neurofibromas located within the iliopsoas muscle, and 1 patient underwent surgery for a pelvic sporadic schwannoma. All tumors were successfully resected, with no complications or postoperative neurological deficits. Preoperative symptoms were improved or resolved in all patients. CONCLUSION: Resection of retroperitoneal nerve sheath tumors confers an excellent prognosis, although their deep location and proximity to vital structures present unique challenges. Robotic surgery with intraoperative neurostimulation mapping is safe and effective for marginal resection of histologically benign or atypical retroperitoneal nerve sheath tumors, providing excellent visibility, increased dexterity and precision, and reduced risk of neurological morbidity.
